Dab tsi yog Magnetic Stirrer Kuj Paub Raws Li?

Magnetic stirrer kuj tseem hu ua magnetic do phaj, magnetic mixer, los yog magnetic stirring hotplate.

Dab tsi yog qhov txwv ntawmmagnetic stirrers?

Sib nqus stirrers, tseem hu ua magnetic do daim hlau los yog sib nqus stirrers nrog cov phaj kub, yog ntau yam khoom siv hauv chav kuaj siv los sib tov kua. Lawv muaj ib tug rotating magnetic teb tsim los ntawm ib tug motorized hlau nplaum nyob rau hauv lub platform. Daim teb no tsav cov hlau nplaum sib nqus los yog yoov tshaj cum hauv lub nkoj uas muaj cov kua dej, ua rau lub zog sib nqus.

Txawm hais tias lawv siv dav thiab ua haujlwm zoo hauv kev sib tov sib xyaw, cov hlau nplaum sib nqus muaj qee qhov kev txwv. Ua ntej, lawv feem ntau haum rau cov kua dej uas tsis muaj viscosity. Cov khoom muaj viscosity siab tuaj yeem tsis tuaj yeem sib xyaw zoo vim yog lub zog tsawg dhau los ntawm cov hlau nplaum. Thib ob,magnetic stirrerstej zaum yuav tsis tsim nyog rau daim ntawv thov uas yuav tsum tau tswj meej tshaj stirring ceev los yog kev taw qhia. Cov lus tsa suab uas tsim los ntawm qhov sib nqus sib nqus yog feem ntau ncig thiab yuav tsis haum rau qee qhov kev sim teeb tsa lossis cov qauv me me. Tsis tas li ntawd, sib nqus stirrers raug txwv los ntawm qhov loj thiab cov duab ntawm lub nkoj. Cov thawv ntim tsis xwm yeem lossis loj loj yuav tsis haum rau qhov sib nqus sib nqus kom zoo, ua rau kev sib xyaw ua haujlwm tsis zoo.

Kev txwv viscosity:Sib nqus stirrers tej zaum yuav tsis haum rau kev sib xyaw ua kua kua los yog cov kev daws teeb meem. Lub viscosity ntawm cov qauv tuaj yeem cuam tshuam qhov kev sib hloov ceev thiab kev ua haujlwm ntawm cov hlau nplaum sib nqus, ua rau tsis tiav kev sib xyaw lossis qeeb sib xyaw.

Qauv Loj: Sib nqus stirrersfeem ntau yog tsim los rau kev sib tov me me mus rau nruab nrab cov kua ntim rau hauv cov thawv xws li beakers, flasks, lossis test tubes. Tej zaum lawv yuav tsis tsim nyog rau kev sib xyaw cov ntim loj heev lossis rau cov ntawv thov uas xav tau kev sib xyaw ua haujlwm siab.

Shear Sensitivity:Sib nqus stirrers tsim cov kev sib hloov uas tuaj yeem tsim kev nyuaj siab ntawm cov qauv lom neeg lom zem lossis cov ntaub ntawv tsis yooj yim. Qhov no tej zaum yuav ua rau puas los yog denaturation ntawm biomolecules, cell lysis, los yog cuam tshuam ntawm ilv qauv.

Thaum tshav kub kub Distribution:Sib nqus stirrers nrog cov cua kub sib xyaw ua ke tuaj yeem muaj kev txwv nyob rau hauv cov nqe lus ntawm kev faib hluav taws xob thiab kev sib koom ua ke thoob plaws lub tshuab ua kom sov. Hotspots los yog kub gradients tej zaum yuav tshwm sim, tshwj xeeb tshaj yog nrog loj los yog irregularly zoo li lub thawv, cuam tshuam qhov sib xws ntawm cua sov.

Sib nqus cuam tshuam:Sib nqus stirrers tuaj yeem cuam tshuam nrog qee yam ntawm cov khoom siv sib nqus-rhiab lossis kev sim, xws li magnetic resonance imaging (MRI) cov cav tov lossis kev soj ntsuam sib nqus. Magnetic teb generated los ntawm stirrer yuav cuam tshuam los yog distort magnetic teb nyob rau hauv ib puag ncig.

Lub taub hau Static:Sib nqus stirrers cia siab rau kev txav ntawm cov hlau nplaum sib nqus los tsim kev sib xyaw ua ke. Qee qhov xwm txheej, tshwj xeeb tshaj yog cov kua dej uas tsis muaj viscosity lossis qis qis qis, "lub taub hau zoo li qub" tuaj yeem txhim kho, qhov twg cov txheej txheem ntawm cov kua tseem tsis sib xyaw ntawm qhov chaw vim qhov tsis txaus ntshai.

Cov teeb meem kev sib raug zoo: Sib nqus stirrerstej zaum yuav tsis haum rau txhua hom ntim khoom lossis cov nkoj. Piv txwv li, cov thawv ua los ntawm cov khoom tsis sib nqus xws li txhuas lossis qee yam yas yuav tsis ua haujlwm nrog cov hlau nplaum sib nqus tshwj tsis yog siv cov khoom sib nqus coated nrog cov khoom sib nqus.

Kev Kho Kom Zoo:Sib nqus stirrers xav tau kev saib xyuas thiab tu kom zoo kom ua tau zoo thiab ua haujlwm ntev. Cov hlau nplaum nplaum nplaum tuaj yeem khaws cov khoom seem lossis cov kab mob sib kis thaum lub sijhawm, yuav tsum tau ntxuav lossis hloov pauv. Tsis tas li ntawd, kev txav mus los thiab cov khoom siv cua sov tuaj yeem xav tau kev tshuaj xyuas thiab kev pabcuam ib ntus.

Cov ntaub ntawv dab tsi yog siv rau hauv magnetic stirrers?

Sib nqus stirrers yog tsim los siv ntau yam ntaub ntawv los xyuas kom meej durability, stability, thiab zoo sib tov. Cov khoom tseem ceeb ntawm lub tshuab magnetic stirrer muaj xws li:

Base:Feem ntau ua los ntawm cov khoom siv ruaj khov xws li stainless hlau lossis txhuas los muab kev ruaj ntseg thiab kev txhawb nqa rau lub tshuab hlau nplaum sib dhos.

Platform: Lub platform uas lub nkoj uas muaj cov kua dej tso rau feem ntau yog ua los ntawm cov khoom siv tshuaj lom neeg xws li ceramic lossis tempered iav. Cov ntaub ntawv no ua kom muaj kev sib raug zoo nrog ntau yam ntawm cov kuab tshuaj thiab cov tshuaj reagents uas feem ntau siv hauv kev sim kuaj.

Motorized hlau nplaum sib dhos: Muaj lub cev muaj zog thiab sib nqus sib nqus, cov khoom no feem ntau yog ua los ntawm cov hlau nplaum zoo xws li cov hlau nplaum neodymium. Cov hlau nplaum no muab cov hlau nplaum muaj zog thiab zoo ib yam tsim nyog rau kev sib tw kom zoo.

Tswj:Tswj vaj huam sib luag los yog pob qhov rooj feem ntau yog ua los ntawm cov yas lossis hlau thiab tso cai rau cov neeg siv los kho qhov nrawm nrawm, qhov kub thiab txias (nyob rau hauv rooj plaub ntawmmagnetic stirrersnrog cov phaj kub), thiab lwm yam tsis.

Dab tsi yog RPM hauv magnetic stirrer?

RPM stands rau "Revolutions Per Minute" thiab hais txog kev sib hloov ceev ntawm cov hlau nplaum sib nqus nyob rau hauv ib qho sib nqus stirrer. Nws qhia tias muaj pes tsawg revolutions lub do bar ua nyob rau hauv ib feeb nyob rau hauv tus ntawm lub rotating magnetic teb generated los ntawm lub motorized hlau nplaum sib dhos. RPM yog qhov tseem ceeb tshaj plaws uas txiav txim siab qhov sib xyaw ua ke hauv kev daws teeb meem. Cov txiaj ntsig RPM siab dua ua rau muaj kev sib xyaw ua ke ntau dua, qhov qis RPM qhov tseem ceeb ua rau muaj kev ntxhov siab. Lub RPM ntawm lub tshuab nqus hlau nplaum feem ntau tuaj yeem hloov kho siv cov kev tswj lossis kev teeb tsa ntawm lub cuab yeej, tso cai rau cov neeg siv los kho qhov sib tov nrawm raws li qhov xav tau ntawm lawv qhov kev sim.

Hauv kev xaus,magnetic stirrersua lub luag haujlwm tseem ceeb hauv chav kuaj los ntawm kev muab cov kev daws teeb meem zoo thiab yooj yim rau ntau yam kev siv. Txawm hais tias lawv cov kev txwv txog viscosity, kev sib raug zoo ntawm lub nkoj, thiab kev tswj xyuas qhov tseeb, lawv tseem yog cov cuab yeej tseem ceeb rau cov kws tshawb fawb thiab cov kws tshawb fawb thoob ntiaj teb.
